Application filed Apri127, 1927. -Sera1,No. 187,035.v

rlhis invention relates to gauges', designed for use by carpenters for locating1andffcut ting the recesses orrsockets,'in which thev leaves of door-butts'may bedis'posed.

The object of the inventionis toprovide a hinge recess gauge or templet, which may be readily applied to door framcs,vas wellV as to the doors, for accurately locating yand gauging the several hinges,the saidf templet being especially adapted forsupportingand guiding -a power-'driven vrouting machine during the cutting of the recesses. A further obJect is to'provide a sectional gauge,

' one section or unit foreach hinge, the said units'be-ing similar .and each being equipped with adjustable means'for laying'outfrecesses of different lengths, `brea'dths and depths, the said units being supported and adjustable towards and from each other, by

means of similar recess-gauging members that overlap each other and' maintain the true alinment of the said units. And ay further object is to provide means for locating and gauging hinge recesses of doors to coinr cide with moldedV recesses of metal frames.

A particular obj ect is to improveand sim# plify the devices lshown and describedinmy United States Patent No. 1,524,234, dated January 25,1925.

The various features and parts of the in= vention will be understood from the detail-ed descriptiorr which follows, and by reference to the accompanying drawings, in which` Figure l is a top plan view of the complete device.

My complete hinge recess gauge usually consists of VVthree-sirnilar sections .or units,as

A,.B.and C, whose frames 4 are preferably Vchannelshaped y'and 'iinterchangeable,4 as

shown Vin Figs. 7 i and ,11, and are provided with lrelatively large medial rectangulaiopenings 4', which.alfordjsuitablev range for the length and breadth of the recesses, asa?,

shown in Figs.f6 andS. .Thev frames4 comprise bottomportion's 4F, land/parallel rails 41?, the bottoms'being recessed longitudinally, as aft-4, to receiveadjstable "endsgau'ging members 5,'by which theupperrnostreces'ses of the frame and door'arel spacedfrom the lintel2. vThe severalframes 4 are connected end to end andsuitablyI `spacedfby means' of similar relatively long' fiatI strips of" metal arranged in pairs', as 6;-6, whose correspond'- ing ends kare over-lapped, and 'areprovided with registering,longitudinall'slots, as Gaf-61), by' which the .severalf.units ,maybe movedl towards and from each other for suitably spacing the hinge recesses. Theplates .t5-Q6 are adjustably held together bybolt-s 7, which play ini the slots Gti-6", andalsopass through and are .suitably spaced by similarelongated spring metal parts 7,`the latter preferably being normally curved,` as shown in '9, and'exerting sufficient tension whenstraightcned out against the plates Y6, to p'revent accidental shifting of the parts.` vThe adjustment ofthe plates 6-46 is "maintainedby wing-nuts 7a, and washers 7b. [Thev'plates (li-f6 are substantially'the same breadth as the channels ,of the frames 4,l and therefore tend to preserve Ithe perfect l alinei'nerit of the units, and their free ends .arel mounted upon the bottoms or webs l4', ,to which. theynre adjustably securedy by means of" screwsj?,

the gauges 5' are engaged with the lintel 2, and the free ends ot the screws 9 are brought into engagement with the edge of the liamb (see Figs. 6 and 7), after which the gauge is temporarily secured to thejamb, by means of nails 10, which are carriedv by the plates 6, 6 and 8. The opposite r'ails'4b are `fitted with `guards 12, which are pivoted by screws 12. .These guards arev relatively thin and provide a/slight clearance between the dooiI and rabbeted or removable stops, as 13 (see Figs. 6 and 7 for preventing chating of the face of the door. The guards 12 also serve to properly position thegauge when the latter is applied to the edge ot the door, as best seen in Fig. 5. rIhe corresponding rails of formed with lugs or bosses 14, which are bored out to receive guard members 14', which are applied to the free ends of sections A and C and extend beyond and prevent `iamming or otherwise disturbing the adjustment ot the end-gauging members v5. i The members 5 are preterably graduated in Ainches and fractions there for enabling the operator to accurately adiust the plates .6 and Sto. hinge butts ot different length, as shown in Figs. 1, 8, 6 and 8. The tree ends ot the members 5 are` cut away to provide two gauging surfaces, as o, 5b, by means of which a slight clearance will occur between the top ot the door 3 and the underside of the lintel 2, as will be understood by comparing Figs. 6 and 8.

Where meta-l door frames are employed, it

l' Vis the usual practice of the abricators to mold or 'depress the hinge recesses in the jambs, thereby rendering `it unnecessary for the builder to rout the frame recesses. In order to adapt my recess gauge to metal frames and at theY same time facilitate the accurate locating ot the recesses in the edge of Vthe door, I -provide transversely disposed gauge members 15 arranged in pairs, which are adjustably mounted upon thefacing ends of the ,plates 6, 6 and 8, by means ot' screws 15', which are threaded into the plates and play in slots 15a formed inV said members. The corresponding ends of the members 1o are formed with gauging points 15C. which Vpass through slots 4dnof the rails 4` and said points beingextended (see Figs. 1 and 3) when the gauge is to be applied to metal frames, and in order to order to properly ydetermine the position of the hinge leaves in 15C, after irstbeing adjusted for butts ota given length, areinserted in the molded recesses, and the gauge is then maneuvered until the points or the spaces between them substantially coincide with the said recesses. The gauge is then reversed and applied to the edge of the door, as shown in Figs. 5

and 8, torlocating and routing the opposing recesses. When the gauge is employed in connection with ordinary wooden door fr ames,"tli.e transverse gauges 15 may be shifted laterally .tor disposing the points `15C in the slots 4d, as shown in Figs. 6 and 8.

Any suitable router may be employed it'oi Stl cutting the recesses, and may comprise a motor 16, the latter being' adjustably supported by a base 16', whose plane bottom is adapted to be slidablypropelled over the top faces of the rails 4". A shaft 17 drives the routing tool 18, the tool projecting below a stationary guide 19 .that engages the margins ot the openings 4 of the units. By this arrangement the recesses a@ are smaller than the openings (see Figs. 6 and 8). rIhe facing edges 15d ot' the points 15c define the longitudinal dimension ot the recesses and correspond to the range of the tool, as regulated by the guide 19.

In my former patent, the gauge members 'A-B are shown connected by means of a rod 5 and sleeves 6, said parts being all located at one side of the gauge. This method of connecting and supporting the gauge members has caused considerable trouble and annoyance, because the rods 5, being round and necessarily small in diameter are easily sults in throwing said members out of alinement, and otherwise distorting the device, to an extentthat renders it ditlicult to prop erly apply the gauge to the frames 'and doors, and effect accurate gauging and routing of the recesses. In the present case, the plates 6 6', whichvtake the place of the old rods (5), are operatively fitted into the channels of frames 4, and said parts may be lmoved longitudinally without disturbing the alinement of the Jframes, and when the adjusting screws are tightened, the device will witlistand considerable rough Vhandling and use, without danger ot distorting the device. The relatively broad connecting plates render it impossible to flex the gauge laterally, and since the said plates are reinforced by being overlapped, as well as by the relatively broad seats atforded by the frames 1-,fthere is no danger ot the parts being bent or other- -wise rendered unserviceable.

medial openings after-cling play for a routing tool, plates Varranged in pairs registering with the channels o'tand adjustably-secured to cach member adjacent themedial opening, certain of said plates extending beyond said members being overlapped and slotted for rendering the plates extensible, and means for clamping and preserving the alinement of the plates.
